[jira] [Created] (HBASE-11368) Multi-column family BulkLoad fails if compactions go on too long

stack created HBASE-11368:
-----------------------------

             Summary: Multi-column family BulkLoad fails if compactions go on too long
                 Key: HBASE-11368
                 URL: https://issues.apache.org/jira/browse/HBASE-11368
             Project: HBase
          Issue Type: Bug
            Reporter: stack


Compactions take a read lock.  If a multi-column family region, before bulk loading, we want to take a write lock on the region.  If the compaction takes too long, the bulk load fails.

Various recipes include:
+ Making smaller regions (lame)
+ [~victorunique] suggests major compacting just before bulk loading over in HBASE-10882 as a work around.

Does the compaction need a read lock for that long?  Does the bulk load need a full write lock when multiple column families?  Can we fail more gracefully at least?
